BY f l f l 7' v70Vl United States Patent SPINNING RINGS Charles Fillinger, Cheektowaga, N. Y., assignor to Herr Manufacturing Company, Inc., Bulalo, N Y.

Application September 23, 1955, Serial No. 536,084 6 Claims. (Cl. 57120) This invention relates to the art of spinning yarns, and particularly to the lubrication of rings used on yarn spinning and twisting machines. y

Spinning rings of this type have heretofore generally been provided on the surface or surfaces thereof contacted by the traveller with one or more holes or openings are `ranged at intervals along such surfaces in which wicks were provided to carry the lubricant to thev traveller. The traveller was then depended upon to carry the lubricant to other parts of these ring surfaces. These holes, ofcourse, provided breaks in the surfaces contacted by the traveller and, consequently, these holes and the wicks would interfere with the smooth operation of the traveller by causing it to vibrate, to break or to fly off from the ring. Rings of this type therefore, limit the speed at which the travellers can be operated.

It is, consequently, one of the objects of this invention to provide `improved means for lubricating these rings in which the breaks in the ring surfaces are eliminated and in which lubricant is supplied to all parts of the ring surfaces contacted by the traveller, this beingpreferably accomplished by providing these surfaces of the rings with capillary seams through which the lubricant passes to these surfaces of the rings.

It is also an object of this invention to provide rings of this type with continuous seams of such small size .that lubricant will pass through the same to the surface to be lubricated Without forming a concave meniscus which would prevent the oil from passing to the traveller.

A further object is to provide lubricating means of this type which provide a uniform, thin film of lubricant on the surface or surfaces contacted by the traveller, thus assuring uniform and eicient lubrication and saving of lubricant as well as making possible higher speeds of the traveller which in turn results in increased production of yarn, less breakage of the yarn, and cleaner yarn by reducing the amount of lubricant which might contaminate the yarn.

Other objects and advantages will be apparent from the following description of one embodiment of the invention and the novel features will be particularly pointed out hereinafter in connection with the appended claims.

In the accompanying drawings:

`Fig. l is a fragmentary side elevation, partly in section, of a part of a spinning machine showing a spinning or guide ring and the parts associated therewith.

' Fig. 2 is a top plan view, on an enlarged scale, of a ring embodying this invention, and mounted on its holder.

Fig. 3 is a central sectional elevation thereof, on a still larger scale showing the ring and its holder in relation to a take-up spool.

Figs. 4, 5 and 6 are similar views showing rings of vvPatented Feb. 3, 1959 ICC spools are mounted on a stationary support or machine part 15. The numeral 16 represents a vertically reciprocating bar having openings 17 through which the spools extend. Mounted on top of the reciprocating bar 16 and extending about each hole 17 thereof are spinning rings 18, one of which is shown in Fig. l. Each ring is mounted on an annular holder 19 secured in any usual manner to a bar 16 of a spinning machine.

The numeral 20 represents a wire traveller which is mounted to revolve on this spinning ring. The wire traveller in the construction shown is formed to have a portion thereof engage an inclined top bearing surface 22 of the ring and a downwardly and outwardly inclined inner bearing surface 24. j

I have found that When two metal parts are placed in contact with each other, the seam or joint between these parts will permit lubricant of the type used on these rings and travellers to pass by capillary actionv through such seam in quantity suicient to adequately lubricate the ring surfaces with which the travellercontacts.

- The spinning rings in the various constructions shown are, consequently, made to incorporate this finding therein, and for this purpose, are made in two parts 25 and 26, the outer part 25 being the main body portion of the ring and the inner ring part serving to form with the outer part one or more capillary seams. This body portion is provided on its inner surface withan annular recess or rabbet 28 .in which the inner ring part 2.6 seats. The inner ring p'art does not completely fill the annular recess, thus leaving an annular hollow groove or channel. 29 after the inner portion of the ring has been assembled in the recess 28.

The inner ring part 26 is formed to fit snugly in the inwardly extending recess 28 in the main body portion of the ring in such a manner that a capillary channel 30 is formed between the upper portion of 'the inner ring part 26 and an inwardly extending shouldered portion 32 formed along the upper edge of the recess 23 of the body portion of the ring. A similar capillary seam 33 is formed between the lower portion of the inner ring part 26 and the horizontally extending portion of the shouldered recess or rabbet 28. It will be undesrtood that the vinner ring part is pressed into the rabbet 28 of the body portion of the ring and is secured in place in any suitable manner. For example as shown in Figs. 2 to 5, the metal of the inner ring part may be peened or otherwise forced outwardly at intervals to extend under the shoulder 32, as shown at 34. The bearing portions of the inner and outer ring lparts are then accurately machined smooth to form good-bearing surfaces. Consequently, along the surfaces at which the body portion and inner ring part contact, only very fine capillary seams will be provided. These seams, after the ring has been assembled and after the contact or bearing surfaces 22 and 24 have been machined, are so minute that they are ditiicult to see. .These minute seams in the spinning ring permit lubricant to flow through the same by capillary action and this lubricant is, consequently, supplied at the outer edges of these seams substantially throughout the entire circumference of the contacting or bearing surfaces. Consequently, the lubricant will be supplied to a bearing surface in small quantities but throughout the circumference of the same, and this lubricant is spread by the traveller throughout the entire area of the ring surface so that a very uniform lubrication of the bearing surfaces results. Because of the limited supply of lubricant through these capillary channels, there will be no excess lubricant which might contaminate the yarn,

andfurthermore; the seams'are so small that therefi's no the passages 37 and 38 into the channel 29.

' substantial flow of lubricant from the seams to the bearing surfaces except by contact of the traveller with the outer edge of the seam. The traveller, consequently, has a slight drawing action which removes klubricant from the outer edge of the seam and spreads it over the bearing surface.

It is necessary that the seams be very small in Width and for that purpose, a press t is preferably provided between the two parts of the ring which form the seam. lf a substantially larger seam or space is provided, the oil will not pass through the same by capillary action, and a concave meniscus may form at the outer edge of the seam, which would prevent contact of the oil or lubricant by the traveller.

Lubricant may be supplied to the groove or channel 29 in any suitable or desired manner. Since wicks have commonly been used heretofore to supply lubricant to the bearing surfaces of these rings, I have shown wicks used for this purpose to supply lubricant from a cup or well 35 of any usual or suitable construction, such for example as have heretofore been employed for this purpose. One or more wicks 36 extend into the lower part of this cup or well and upwardly through a passage 37 in the holder 19 which joins a passage 38 formed in the body portion of the spinning ring and which terminates in the lubricant receiving channel 29. It has been found that by this construction, the wick 36 carries lubricant into the receiving channel 29 to supply both of the capil lary seams. In the construction shown, the inner ring 26 is provided with a hole through which the end of the wick extends. This hole is provided so that a wire or other member can be passed through the same and connected with the wick 36 for drawing the wick through it will be noted, however, that this wick and the hole through which it passes is not contacted by the traveller 29, and the wick does not terminate at any of the 'bearing surfaces of the spinning ring. rl`he quantity of lubricant supplied to the channel 29 can be controlled as heretofore by `varyin.U the density of the wick, it being obvious that if this wick fits tightly into the passages through which it extends, it will conduct less lubricant `to the channel 29 in which the wick fits loosely in the channels 37 and 38.

The construction of the cup or well may, for example, be as shown in my Patent No. 2,333,069, but cups or wells of any other suitable constructions may be employed, if desired.

The construction shown in Fig. 4 differs from that shown in Figs. l to 3 in that an additional ring or washer 40 is provided between the lower edge of the inner ring part di and `the main or body portion 42 of the spinning ring. This ring or washer 4t) is preferably also made of metal and is employed when it is desired to provide more lubricant to the lower bearing surface ofthe spinning ring, since by this construction, two capillary seams are provided for this bearing surface in place of the single seam shown in Figs. 2 and 3. Otherwise this construction may be the same as that referred to in the preceding description.

In the construction shown in Fig. 5, a supply channel 45 much larger in size is provided in the main body portion 46 of the spinning ring and this channel may contain suitable fibrous material 47 for supplying the lubricant to the two seams of the spinning ring between the body portion 46 and the inner ring portion 48 thereof.

While in the construction shown in Figs. 1 to 5, I have shown my improvements applied to traverse or spinning rings having two bearing surfaces with which the traveller contacts, yet it will be obvious that my invention is equally applicable to such rings having a single bearing surface, such as shown in Fig. 6, in which a bearing surface 50 is provided, with which a traveller 51 of different form cooperates. In this construction, the body portion 52 of the spinning ring is provided with a channel 53 which is closed when the inner ring part 54 is pressed into engagement with the body portion 52 of the ring. Lubricant may be supplied to the channel 53 by means of wicks as in the other constructions shown. A minute seal is also formed between the outer edge of the inner ring part 54 and an upwardly extending part of the main ring part, but the traveller will not pass over the outer edge of the same, and consequently, no appreciable amount of lubricant will be discharged through this seam.

It will be noted that in each of the constructions shown, the capillary seam at the larger or upright bearing surface of the spinning ring which faces inwardly is located at the upper portion thereof to facilitate the distribution of lubricant to all parts of the inner bearing surface of the spinning ring.

The spinning ring may be made in part from powdered metal so that the capillary feeding of lubricant to the bearing surfaces of the ring may be effected by lubricant passing through the minute interstices or seams between the particles of the metal leading to a bearing surface.

The construction described by means of which lubricant is passed through capillary seams or interstiees has decided advantages over lubricating means including holes tenninating at the bearing surfaces of the rings and through which wicks extend. Since the travellers move at high rates of speed, it will be obvious that very slight irregularities in the bearing surfaces contacted by the travellers will produce vibrating, rattling or other irregular movements of the travellers, which results in damage to the travellers as well as to the spinning rings and also in frequent tearing of the threads, which in turn results in a `temporary shut-down of a part of a spinning machine. Furthermore, by means of these prior constructions, it was found that frequently the distribution of lubricant was not uniform on all parts of the bearing surfaces with which the travellers Contact. This, of course, resulted in rapid wear of .the travellers as well as of the spinning rings. Ey means of the construction herein described, uneven lubrication of the bearing surfaces is avoided, since the lubricant need only be moved through short distances by the travellers from the lubricating seams. This fact makes it possible to use smaller quantities of lubricant than has been heretofore possible, and this in turn has the advantages not only of reducing the cost of lubricant applied on the spinning machines, but also by avoiding excess lubricant on .the spinning rings, the risk of contaminating the threads with lubricant is Very greatly reduced. However, the main advantage of the construction described is that the uniform lubrication of vthe bearing surfaces with which the travellers contact results in a smoother operation of the travellers, which makes it possible to operate the travellers at higher speeds, thus increasing the production of yarn `by a machine equipped with my improved traverse or spinning rings.

It will be understood that various changes in the de tails, materials, and arrangements of parts which have been herein described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art Within the principle and scopeof the invention, as expressed in the appended claims.
